Thanks you very much, the largest bluegills are the same length at 7 inches. They differ in height, Headshaker is the biggest. Big Blue has a small spot of black on near the pelvic fins. Headshaker has a large patch of black in the same area.
The blackness showed up after a major clash months ago. Even though Headshaker has the most black, he won the fight and Big Blue was clearly shaken up. Big Blue left Headshaker alone for a very long time. Of course Big Blue decided to challenge again and Headshaker was ready. Then I separated them to avoid injury. Now they are back together in a larger tank. We will see how it goes, I am preparing just in case.
